I am having problems with the following code. I am trying to update my db table Categories in Northwind. I have borrowed this code from www.dotnetjohn.com/articles/articleid27.aspx Although it works on dotnetjohn website, I cannot replicate the code successfully. I have a datagrid filled with data and two textboxes with an “Insert” button. When the button is pressed, the text entered into the two textboxes is to be added to the table Categories in Northwind db. I cannot get the click event to update the database and add a new record entry. The page_load fills the datagrid with data from a SELECT statement. The Insert_Click should take the entries from two textboxes and insert them into the Northwinds database Categories table. I have enclosed the basic components of my .aspx.vb page for the Page_Load, Insert_Click, and FilltheGrid() method. I am confused as to my problem. Please help. Thank you. If you need more data just ask me to provide it
